Part 3: Tea tree as a viable (yet incomplete) solution to curing scabies

Tea tree oil applied topically: Tea tree oil has frequently been mentioned as a cure for scabies [8], with multiple angles of benefit: first, it can kill the mites. Second, it may help with secondary complications such as with the proliferation of Staphylococcus Aureus and Streptococcus pyogenes [11][21]. Additionally, in one study, it was shown that tea tree oil had not exhibited any cytotoxicity to fibroblast cells [21]. In another study, it was shown that tea tree oil, even at very low concentrations, can inhibit the growth of various types of cancer [23][24][25].

But it isn’t without its limitations. Tea tree’s antibacterial properties may also kill good bacteria such as lactobacillus. By re-introducing good flora to the skin after tea tree oil is washed off, this negative impact may be countered. See Part 2 for details. An additional limitation of tea tree oil is in the potential (albeit low) for skin irritation in some individuals. (Definitely do a spot test before adding this to your regimen). The final limitation to tea tree oil is due to poor absorbency in the skin.

The main issue with tea tree oil is that there is very limited penetration into the epidermis layer of skin in its pure form, and it’s also very quick to evaporate [9]. To know how effectively the tea tree oil should penetrate the skin to provide a cure, it’s important to understand how deep scabies burrow. I’ve read that scabies burrow no deeper than beyond the stratum granulosum layer of the skin, which is part of the epidermis (diagram of skin here) [14, 18]. There are many sources that indicate that the mites primarily burrow in the stratum corneum (several layers above the stratum granulosum), but many which state stratum granulosum, and, if we want to find the most effective solution, it’s best not to assume the best. Therefore, a perfect cure would need to at least be absorbed into the stratum granulosum layer of the skin and remain within that part of the skin (or at least reasonably reapplied to this part of the skin) until all remaining mite eggs have hatched. [Edit] From my understanding, however, once the stratum corneum layer is penetrated, the drug can freely pass through to the dermis. Darn you, stratum corneum!

Overall, to fully eliminate mites, the mite kil

Society needs to open its eyes

People get outrage about what happens before birth, then ignore what's done after. I've seen people get outraged at the POSSIBILITY of fetal tissue being sold and then act like the surgical removal of healthy functional tissue from a healthy infant is a non issue. Here is what most are ignoring:

These are harvested from the healthy foreskin of newborn babies. It's a huge profitable business. When there is a demand, a supply will be found and when most people will not question why a healthy child should have a surgery that is medically unnecessary because it's been normalized over time you will have a great supply available.

[Anti-Aging] Anyone using DMAE products with positive results?

Seems to be a controversial ingredient, but so far it appears to be the only skin-tightening topical other than maybe tretinoin. I’d love to hear from anyone who’s had good results with it.

Brazilian 2009 study showed DMAE increased dermal thickness and collagen fiber thickness.

Johnson & Johnson study tested a 3% DMAE facial gel in a randomized clinical study. Over a 16 week period it was “shown to be safe and efficacious in the mitigation of forehead lines and periorbital fine wrinkles, and in improving lip shape and fullness and the overall appearance of aging skin. These effects did not regress during a 2-week cessation of application.” The study was continued for an additional 8 months with no adverse long term effects.

The only negative study is this one testing DMAE on rabbit fibroblasts and human epithelial cells. Fibroblast mortality (aka cell death) increased by 25% and cell division slowed significantly after application. It also caused vacuolization in human epithelial cells, a process known to occur after cell damage.

Quercetin

Quercetin is a plant pigment (flavonoid). It's found in many plants and foods, such as red wine, onions, green tea, apples, and berries. Quercetin has antioxidant and anti-inflammatory effects that might help reduce swelling, kill cancer cells, control blood sugar, and help prevent heart disease

These properties form the basis for potential benefits to overall health and disease resistance, including anti-carcinogenic, anti-inflammatory, antiviral, antioxidant, and psychostimulant activities, as well as the ability to inhibit lipid peroxidation, platelet aggregation and capillary permeability, and to stimulate mitochondrial biogenesis [2].

Quercetin-type flavonols (primarily as quercetin glycosides), the most abundant of the flavonoid molecules, are widely distributed in plants. They are found in a variety of foods including apples, berries, Brassica vegetables, capers, grapes, onions, shallots, tea, and tomatoes, as well as many seeds, nuts, flowers, barks, and leaves. Quercetin is also found in medicinal botanicals, including Ginkgo biloba, Hypericum perforatum, and Sambucus canadensis [6,7,8]. In red onions, higher concentrations of quercetin occur in the outermost rings and in the part closest to the root, the latter being the part of the plant with the highest concentration [9]. One study found that organically grown tomatoes had 79% more quercetin than chemically grown fruit [10].

Quercetin glycosides might be differently absorbed based on the type of sugar attached [21]. Available evidence indicates that quercetin glucosides (like those found predominantly in onion or shallot flesh) are far better absorbed than its rutinosides (the major quercetin glycoside in tea). The glucosides are efficiently hydrolyzed in the small intestine by beta-glucosidases to the aglycone form, much of which is then absorbed [22]. Quercetin glucuronic acid and its sulfuric acid derivatives were more easily absorbed than quercetin [22]. Thereafter, its absorption is affected by differences in its glycosylation, the food matrix from which it is consumed, and the co-administration of dietary components such as fiber and fat [23]. Thus different sugar types and sugar group conjugation sites will result in absorption variation.

Quercetin and derivatives are stable in gastric acid; however, there were no reports whether they can be absorbed in stomach. Studies suggest that quercetin is absorbed in the upper segment of small intestinal [24,25].

How does spermidine stimulate hair growth and how much more effective is it than minoxidin?

Hair grows in cycle with 3 distinct and concurrent phases, namely anagen, catagen and telogen phases. The anagen phase is also known as growth phase when hair follicles actively divide to form hair. Meanwhile, catagen phase begins when anagen phase ends, it is transitional period when hair follicles undergo apoptosis, disintegrating and cutting of the hair strand from nourishing blood supply. Last, entering into telogen phase, or resting phase when the hair and follicles remain dormant. The cycle starts over when telogen phase finished.

The differentiation and proliferation of hair matrix cells is regulated by a numbers of molecular factors, namely, fibroblasts growth factors (FGF-7), Vascular Endothelial Growth Factors (VEGF), Insulin-like growth factor-1 (IGF-1), hepatocytes growth factors (HGF).

Molecular factors such as FGF-7, VEGF, IGF-1, HGF are involved in the hair follicle growth. The expression of these factors in culture human dermal papilla cells was evaluated. The expression of HGF was up-regulated and showed significant difference. Hepatocytes growth factor (HGF) is a multifunctional polypeptide which was found to stimulate hair follicles growth during anagen phase.

Meanwhile, the expression of FGF-7 was up-regulated in samples containing spermidine 10, 100g/mL, the up-regulation of VEGF and IGF-1 was expressed at concentration of Spermidine-HF 100g/m. Above finding clearly suggested that Spermidine-HF promote hair follicles growth with up-regulation of hair growth promoting factors – HGF, FGF-7, VEGF and IGF-1 respectively.

[Misc] Is PPD truly the last word in UVA protection?

I have a small conflict that I’d love to have explained regarding PPD as an accurate measure of UVA1 rays in the spectrum of 340nm - 400nm.

UVA1 rays at or above 360nm seem to confer the most damage to skin such as induction of matrix metalloproteinases (i.e., MMPs/collagen degradation enzymes) and secretion of inflammatory cytokines. (1)

The Textbook of Cosmetic Dermatology, 2010 Edition, page 201, states that UVA2 is the portion of UVA mostly represented in the PPD testing. (2) Prompting the FDA to propose augmenting the PPD test with additional additional in vitro testing that provides a measure of UVA1 protection, specifically the ratio of UVA1 absorbance to total UV absorbance - which, incidentally, I believe is how it’s measured here in the UK.

Another paper in Sunscreens: Development: Evaluation, and Regulatory Aspects: Second Edition, directly states (p. 570) that About 7% of the total PPD response is ascribed to UVA2 and 92% to UVA1.(3)

These two items above seem to conflict directly. The last piece of information I found that might be helpful is below.

‘The action spectrum of PPD is maximum at short UVA wavelengths and gradually decreases from 320 to 400 nm.’ (4) Since UVA1 long rays begin at 340nm, and rays at or beyond 360nn seem to confer the most damage to skin, I take that to mean PPD is not an entirely accurate measure of protection against upper-end of spectrum UVA1 rays.

Please help me parse this out. I would greatly appreciate it.

(1) Vielhaber G, Grether-Beck S, Koch O, et al. Sunscreens with an absorption maximum of≥ 360 nm provide optimal protection against UVA1-induced expression of matrix metalloproteinase-1, interleukin-1, and interleukin-6 in human dermal fibroblasts.

SERIOUS: This subreddit needs to understand what a "dad joke" really means.

I don't want to step on anybody's toes here, but the amount of non-dad jokes here in this subreddit really annoys me. First of all, dad jokes CAN be NSFW, it clearly says so in the sub rules. Secondly, it doesn't automatically make it a dad joke if it's from a conversation between you and your child. Most importantly, the jokes that your CHILDREN tell YOU are not dad jokes. The point of a dad joke is that it's so cheesy only a dad who's trying to be funny would make such a joke. That's it. They are stupid plays on words, lame puns and so on. There has to be a clever pun or wordplay for it to be considered a dad joke.

Again, to all the fellow dads, I apologise if I'm sounding too harsh. But I just needed to get it off my chest.
